For some passengers who can't buy tickets, they should buy themselves a small stool in advance. When you get on the train, you can find a place to lay a stool. People who have experienced standing home will know how happy it is to have a small stool to sit on the train.
In addition, you can also buy an eye mask, because when we take the bus, the lights in the car are always on, especially when we take the train and the high-speed rail. At this time, you need an eye patch to help you block out the light, so that you can enjoy your good sleep quietly after wearing the eye patch.
